I think supermods are a two sided medal. They can be very disruptive to a community but they are in a way a superhighway for content and a small but growing community with greater ambitions needs nothing more than content. Maybe some of the problems can be avoided with a good culture of communication between mods, admins and community but I think that's very hard to achieve for a content platform that also has to have to some degree keep an eye on rentability.
